Subject Re: CryptDB - FYI - it might be inspirational for Accumulo encryption architecture
Date Tue, 31 Jul 2012 11:35:51 GMT
I have code, which I can share, to
   use a symmetric key to encrypt data in cells
   use a sharable public key to encrypt/decrypt the symmetric keys, so that
data can be shared.

You can use the visibilities to ensure users don't get other users' data,
if you like. Data is encrypted at rest, and with a client, in transit.
